Get Pricejan 20, 2020 crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, step-loading compression tests were conducted on the mixtures of pa-13 and a control asphalt mixture ac-13, respectively.the aggregate crushing value of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kn. apparatus 2.1 An
